Hi Pyomo development team,
The recent versions of GAMS (v46+) incorporate GUROBI v11 which support solution of NLP/MINLP models directly. However, invoking GUROBI through GAMS in Pyomo results in '…

Hi, Thanks for the code provided for Google Colab.
I am trying to solve my MINLP problem using 'couenne'. It takes a long time until it gives me the result; however, I want it to stop computations af…

I want to incorporate a MINLP solver for my web app, and it seems that SCIP is a good choice, but the architecture is a bit too complicated for me to figure out how to build it into WebAssembly with […

## Summary
The GDPopt LBB algorithm does not find a solution for a problem where the Boolean solution is already fixed.
### Steps to reproduce the issue
```
m = ConcreteModel()
m.x = Var(bo…

Hi,
thanks first for the nice package.
I tried to set up a simple MINLP by the help of the README, but it fails with the following error message:
`ERROR: LoadError: The solver does not support an…

In Julia we can currently send MINLPs to MINOTAUR via [AMPL NL files](https://github.com/JuliaOpt/AmplNLWriter.jl). However, there can be advantages in accessing MINOTAUR directly as an NLP solver in…

https://github.com/lanl-ansi/Alpine.jl/issues/223 rises from the grave.
I don't remember if we support user-defined functions, but we should at least throw a nicer error message:
```Julia

Hi,
for the upcoming INFORMS annual meeting we are presenting the results of our [convex MINLP solver benchmark](https://doi.org/10.1007/s11081-018-9411-8).
We want to show some updated numbers for …
